Question

Чему будет равно значение переменной S, после работы программы, представленной в виде блок-схемы, где div - оператор целочисленного деления? S:=1024 i:=1 to 10 s:=s div 2 S

Answer 1

1) i:=1 s:=1024 div 2=512
2) i:=2 s:=512 div 2=256
3) i:=3 s:=256 div 2=128
4) i:=4 s:=128 div 2=64
5) i:=5 s:=64 div 2=32
........................................
10) i:=10 s:=2 div 2=1
или 1024=2^10 следовательно, после 10 итераций ответ будет равен 1.
Ответ: s=1

Answer 2

Program Analysis

The given program is represented in the form of a block diagram, and it involves the following operations: - `S := 1024` - `i := 1 to 10` - `s := s div 2` - `S`

Variable Calculation

The value of the variable S after the program's execution can be calculated by analyzing the given operations.

1. Initialization: - Initially, the variable S is assigned the value 1024.

2. Loop Operation: - The variable i is iterated from 1 to 10. - During each iteration, the value of S is updated by performing the operation `s := s div 2`.

3. Final Value: - After the loop, the final value of S is obtained.

Calculation Process

The calculation process involves updating the value of S during each iteration of the loop, where the operation `s := s div 2` is performed.

Conclusion

The final value of the variable S after the program's execution can be determined by considering the initial value of S and the effect of the loop operations.
